. In most s ituations in ER modeling with fixed (and often small)
J, the LS estimates are inconsistent when n . When treating u
i
as an
random effect, however, the MLEs for all model parameters are consistent,
hence it is a practical choice. How to treat y
i0
s in the model is sometimes an
important issue. See Hsiao (2003) for details.
When u
i
is considered random, this model can be written as a marginal
